      <tr>
       <td>name</td>
       <td>
        The name element contains the username of the user. This is
        a short, usually less than 16 character &quot;handle&quot; of the
        user, not the real, full name. This should be the same as
        the <code class="parameter">username</code> parameter used when
        calling the function, and hence redundant.
       </td>
      </tr>

      <tr>
       <td>passwd</td>
       <td>
        The passwd element contains the user&#039;s password in an
        encrypted format. Often, for example on a system employing
        &quot;shadow&quot; passwords, an asterisk is returned instead.
       </td>

       <td>uid</td>

        User ID of the user in numeric form.

      <tr>
       <td>gid</td>
       <td>
        The group ID of the user. Use the function
        <span class="function"><a href="function.posix-getgrgid.html" class="function">posix_getgrgid()</a></span> to resolve the group
        name and a list of its members.

      <tr>
       <td>gecos</td>
       <td>
        GECOS is an obsolete term that refers to the finger
        information field on a Honeywell batch processing system.
        The field, however, lives on, and its contents have been
        formalized by POSIX. The field contains a comma separated
        list containing the user&#039;s full name, office phone, office
        number, and home phone number. On most systems, only the
        user&#039;s full name is available.
       </td>
      </tr>

      <tr>
       <td>dir</td>
       <td>
        This element contains the absolute path to the home
        directory of the user.

      <tr>
